Does RRAS work with IIS?

It will force you to install IIS, which is odd, because RRAS can work independently of IIS (you can even stop and disable IIS and RRAS will still work). I would think just the IIS Hostable Web Core would be enough, but whatever. It’s required. Go ahead and accept that it will be installed.

Certificate Expiration

Of course, all certificates expire, and the TLS certificate used for SSTP is no exception. When using a public TLS certificate, the certificate lifetime is typically no more than one year, which means Always On VPN administrators will be renewing this certificate regularly.

Certificate Renewal

The process of “renewing” an SSTP TLS certificate is essentially the same as installing a new one, as it is best to create a new public/private key pair when renewing a certificate.

Demonstration Video

A recorded video demonstration of this process can be found here. The video recording also includes guidance for making these changes on Windows Server Core servers.
